Boston, lin' the county of Suffolk and State of Massachusetts, haveinvented, a new and Im.

proved :Portable Cooking-Range, for the use of armies in campand iield[and in other similar situations ,and I do hereby declarel that thefollowing isa full and exact description thereof, reference heingvhad tothe accompanying drawings, makingpart of this specification- Figure 1being a front elevation of my im- -proved army-range Fig. 2,' a top Viewthereof; Fig. 3, a central vertical section thereof, to-- geth-er'withits oven,.in place. .4

' Like letters designateV corresponding parts in 'all'of the igures.-

'-'Th re are several desiderata 'in a-good army- Arange which it isnecessaryito'supply to in. jsur'eV complete succes's,"'andi thesedesiderata mustbe considered not only singly, but in'all oftheir'severalA and mutual relations, so as toU harmonize together, inorder to produce the best el'ect.- ylhe tirstgeneral,desideratumfiscomplete portabilit y, which includes lightness, compactness, andconvenience of packing, handling, setting up, and taking apart vfortransportation; second, adaptability iu its operation to its proposeduses, including capability of successful workingin all places howeverltrough'- and inconvenient, suitability for the various kinds of cooking,and in the use and lapplication of its furniture; third, simplicity ofconstruction and operation, sucient" strength and durability. 4

Myinvention is intended to fulfill all of these conditions in the mostdirect and 'efficient manner, and is tofbe considered in this view as awhole in all the relations and results of its several parts.

Inorder to give it the greatest capacity with the least Weight and bulk,in view of its portability-,I make the body A broad and loW, the heightbeing, just suicient only to allow the necessary space for fuel ivithin;and itsutensils composing its furniture are arranged so 'asto occupylittle or noue of the internal space.` This Jtbrm also imparts thelargest portion of the heat to. the -useful top surface,

and 'least to` lateral useless radiation. The

form is cylindrical, as being the best for strength, compactness,and-convenience. The material yis sheet-iron, being light, not liablebreak, and suiciently rigid and firm to re- 4amg-les to its surface;into` the upper end ofthe cylindrical -bodyj-A,

andthe top is 4thereby held. in place without anyjastening, and thustting into the sheet- 'ronfbody keeps thersame stretched-:out in -goodform, so asl thereby to impart to it all the vfirmness andstrength-lever,4 required.4 .This simple method of uniting the topand'body affords the utmost facilityv for setting up the i j sistinjurious indentation and ,bruising. 4

only requires to be stitened at-th'eloweredge by a single hoop,fa,ofironrivetedtoit." A0in `account of the situations where itisintended, to be used, it requires no bottom ,izvhich would Io nly add toits Weight;v and; would diminish its `.c ompactness. But'ffor 'specialuses `a bottom may be addedit desired, being constructed and attachedsubstantially vin the manner of the top B, whichconsistsof-a planediskof caste. iron, either in one piece or in two' pieces riv-Veted-togethelgas shown in thejdrawings.Y

This .top is provided with a ange, 11, close to it'souter edge,projecting downward .at-right The ange fits closelyrangeaud taking itapart again for transportation. It also 4allows the furniture tobeVreadily/ packed inside of thebody, and the top to be simply laid overor under all. The articles are also readily removed again therefrom. Thetop has a suitable number ofboiler-holes with covers in the usualmanner, and a thiinble is riveted to the body A to receive thesmokevpipe C. .The range being constructed thus with a view toconveninceand compactness,

for portability, the furniture is nested together as Well as thesmoke-pipe, by having the successive numbers or joints alittle smallerthan the preceding, They are allot such 'size and so arranged 'as to beplaced inside ofthe rangebody A, and the' Whole are' packed in a boxmade just large enough to receive the'range.

A box forty` inches long, .thirty-eightinches wide, and eighteen inchesdeep will'holdia' range and all its furniture and apparatus com'- plete,sufficient to do `all the cooking for a company of one hundred men upon,the whole range and apparatusweighing only `three hun- .dred pounds. Therange can be unpacked and set up ready for use in five minutes, andrepackedin three minutes. i' f i The range, as thus' far described, isnot prepared for'baking. I combine'an oven, D, Fig.
